This is the perfect time to service the wastewater pumping systems

When gravity drainage from kitchens or catering areas is not available, a wastewater pumping system is required. This is a typical situation in a small commercial kitchen.

The sinks and dishwashers are connected to DrainMinor and DrainMajor automatic pumping systems, manufactured and supplied by leading independent wastewater pumping experts Pump Technology Ltd.

As with any wastewater pumping system, particularly those in a busy commercial kitchen, it is recommended that the equipment is regularly inspected and any debris removed before it can build up and eventually clog or even break the pump. In this case a relatively simple task since the tanks for these units are constructed from polyethylene, with a sturdy encapsulated seal. The lid is held in place by four thumb screws; therefore, no tools are required for a simple inspection.

like many catering sites, this one contracted Pump Technology Services Ltd. (the National service division of the company) for their dedicated maintenance, repair and after-care services.

Daryl Hall, General Manager of this division says: “We normally suggest either six monthly or yearly services to our catering clients depending on the kitchen usage and food types.

Grease and fats in particular can build up very fast and result in the pump becoming much less effective. This can manifest itself in more stop/starts, a less accurate on/off position of the float arm and eventually clogging of the pump. All of these situations adversely affect its life and reliable operation.

The pictures show the DrainMajor before and after maintenance. The compact DrainMinor, which is not being protected by an upstream grease trap, needs much more attention than the DrainMajor with its larger capacity tank. and protective grease trap.

During service the vent filter on the DrainMinor was renewed. In this installation the DrainMajor was vented directly to external air, but had it been vented internally, it’s Microvent active carbon filter would also have been replaced.

With the correct inspection and appropriate maintenance, the pumping system will provide years of trouble-free operation, which is why these units are the choice of many leading kitchens as well as fast food and coffee chains.
